?AIM: To investigate NO levels in tears and anterior chamber inflammation after phacoemulsification and intraocular lens implantation with trabeculectomy through different operative incisions.?METHODS: Totally 49 patients ( 50 eyes ) with primary acute angle - closure glaucoma and cataract were randomly divided to single-incision group and double-incision group. Both were treated by phacoemulsification and intraocular lens implantation and trabeculectomy after routine IOP-lowering drugs treatment. Preoperative and postoperative NO levels in tears were compared, and the aqueous flare and cells were examined using a laser flare-cell meter ( LFCM) .?RESULTS:Postoperative tear NO was 9. 86±0. 78μmol/L in single-incision group , it was 9. 13 ± 0. 67μmol/L in double-incision group, the differences was statistically significant(t=3. 57,P<0. 05). Postoperative aqueous flare values was 62. 42±18. 16 pc/ms in single-incision group;it was 52. 20 ± 17. 57 pc/ms in double-incision group, the differences was statistically significant(t=2. 02, P<0. 05).?CONCLUSION: The early inflammatory injury of double-incision was significantly lower than that of single -incision. It has the advantages of safety. But the surgical skill should be improved to less the injuries caused by operations.

OBJECTIVETo observe the therapeutic effect of Hongbeiyegen [the root of Alchornea trewioides(Benth.) Muell.-Arg.] on alcohol-induced liver fibrosis (AF) in rats and explore its mechanism.

METHODSIn rats with AF, the serum levels of transforming growth factor beta1 (TGFbeta1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were detected along with examination of the changes in serum hyaluronic acid (HA), laminin (LN), procolagen type III (PC III), collagen type IV (C IV), glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) levels.

RESULTSCompared with the control group, Hongbeiyegen could significantly reduce the levels of TGFbeta1, TIMP-1, HA, LN, PC III, CIV, ALT and AST in rats with AF.

CONCLUSIONHongbeiyegen can relieve and ameliorate liver fibrosis possibly by inhibiting the expression of TGFbeta1 and TIMP-1.

OBJECTIVETo assess effect of acupuncture combined with massage of sole on sleeping quality of the patient with insomnia.

METHODSFifty-eight cases of insomnia were randomly divided into an observation group (n = 32) and a control group (n = 26). The observation group were treated with oral administration of Alprazolam, massage of sole, and acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), etc. on the abdomen as main points; the control group were treated with Alprazolam. Clinical therapeutic effects, and scores for Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were assessed before and after treatment in the two groups.

RESULTSThe effective rate was 93.75 in the observation group and 88.46% in the control group with no significant difference between the two groups; after treatment, there were significant or very significant differences in scores for various factors in the PSQI, SAS and SDS (P < 0.01, P < 0.05).

CONCLUSIONAbdominal acupuncture as main combined with massage of sole can obviously improve sleeping quality of the patient with insomnia.

OBJECTIVETo study the correlation between noise and blood pressure and/or hypertension, and its age characteristic.

METHODSThe pure tone audiometric and blood pressure examinations were performed in 14537 workers from 157 factories. Hearing impairment was used as a surrogate indicator of cumulated noise exposure. The associations of hearing impairment and duration of noise exposure with blood pressure and hypertension were analyzed respectively after age and gender stratification.

RESULTSMost of the objects were males (81.2%), younger than 35 years old (77.8%), and the duration of exposure to noise was less than 5 years (73.6%). The prevalence of hearing impairment in males was significantly higher than that in males, and increased with age and duration of noise exposure. Only in males with age younger than 35 years old, the systolic and diastolic blood pressures of subjects with sensorineural hearing loss significantly enhanced, and the diastolic blood pressure and prevalence of hypertension increased with duration of noise exposure. The risk of hypertension in males with sensorineural hearing loss significantly increased, the odds ratios in subjects with age younger than 35 years old and with age older than 35 years old were 3.0 (95%CI: 1.5 ∼ 6.1) and 2.1 (95%CI: 1.2 ∼ 3.4), respectively.

CONCLUSIONThe severe hearing impairment induced by noise was associated with hypertension. It is suggested that people should pay attention to the effects of noise on hypertension in young workers.

OBJECTIVETo isolate viruses from mosquitoes in the south of Xinjiang and identify these viruses primarily.

METHODSA total of 13 491 mosquitoes were collected in the south of Xinjiang from Jul to Aug, 2005. These mosquitoes were divided into 130 groups and grinded respectively. The supernates were inoculated in C6/36 and Vero cells. Viruses isolated were detected, the genomic nucleic types by electrophoresis of viral genomes and the morphologies observed under electronmicroscope.

RESULTSAll 42 viruses were isolated, which caused CPEs on C6/36 but not on Vero cells. 27 viruses showed similar genomic profiles with 12 dsRNA segments. 1 virus displayed genomic profile with 10 dsRNA segments. 5 viruses took on similar genomic profiles with about 4 kbp DNA band. 9 viruses did not get any taxonomy information. Electromicroscopic pictures of these viruses revealed that above four types of viruses had distinguished morphologies indicating different virus species.

CONCLUSIONThere should be several virus species in the mosquitoes in the south of Xinjiang. dsRNA virus with 12 genomic segments should play analysis a predominant role in the south of Xinjiang.

OBJECTIVETo establish a method of indirect immunofluorescence (IIF) to measure DNA (mDNA)-associated autoantibodies to cell membrane, and to evaluate diagnostic value of the anti-mDNA antibodies in patients with juvenile systemic lupus erythematosus (SLE) in comparison with anti-dsDNA antibody.

METHODSForty-four children with SLE were enrolled in this study. As a control group, 30 children with other rheumatic diseases were also enrolled. Anti-mDNA and anti-dsDNA antibodies were measured by IIF. Anti-smooth muscle (Sm) antibodies were measured by immuno-double diffusion (ID) and IIF.

RESULTSOut of 44 juvenile SLE patients, 34 (77.27%) were seropositive for anti-mDNA, which was significantly higher than that of patients with other rheumatic diseases (20.00%, P<0.05). The sensitivity and specificity of anti-mDNA for juvenile SLE diagnosis were 77.27% and 80.00%, respectively. The positive predictive value and negative predictive value were 85.00% and 70.59%, respectively. The positive rate of anti-mDNA in SLE lacking of anti-dsDNA and anti-Sm antibodies were 68.00% (17/25) and 79.49% (31/39), respectively.

CONCLUSIONThe detection of anti-mDNA antibodies is useful for diagnosis of juvenile SLE, especially in patients who are negative for anti-dsDNA antibodies and anti-Sm antibodies.

OBJECTIVETo investigate the mRNA expression of matrix metalloproteinase 1 (MMP1) gene in oral squamous cell carcinoma (OSCC) and the paired normal tissues.

METHODSThe differential expression of MMP1 mRNA between 30 OSCC and paired normal tissues were detected with reverse transcription-PCR (RT-PCR).

RESULTSThe relative expression level of MMP1 mRNA in the OSCC tissues showed a 3.26-fold increase in comparison with that in the paired normal tissues (4.06-/+0.52 vs 1.24-/+0.17, P<0.0001). In the 30 OSCC tissues, the relative expression level of MMP1 mRNA was higher in histological grade II/III tissues (4.31-/+0.68) than in grade I (3.87-/+0.57) tissues, higher in OSCC in advanced stages (III/IV) than in tumors in early stages (I/II) (4.18-/+0.67 vs 3.65-/+0.53), and also higher in OSCC with cervical lymph node invasion than in those without cervical lymph node invasion (4.32-/+0.71 vs 3.91-/+0.51), but these differences were not statistically significant (P>0.05).

CONCLUSIONMMP1 gene may play a role in local invasion of OSCC, and can serve as a potential biomarker molecule for diagnosis, treatment and prognostic evaluation of OSCC, with also clinical value for OSCC classification.

OBJECTIVETo investigate the mRNA expression of collagen genes in oral squamous cell carcinoma (OSCC) and paired normal oral mucosal tissue.

METHODSThe differential mRNA expressions of collagen genes between 30 OSCC tissues and the paired normal oral mucosal tissues were detected by RT-PCR.

RESULTThe relative expression level of COL1A1 mRNA in the 30 cancerous tissues was up-regulated by 2.78 folds as compared with its expression in the paired normal samples, suggesting its significant overexpression in OSCC (P<0.001). The expression levels of COL1A2, COL4A1, COL4A2, and COL5A2 mRNA in the cancerous tissues were up-regulated by 1.07, 1.15, 1.27, and 1.16 folds compared to those in paired normal samples (P>0.05).

CONCLUSIONCOL1A1 mRNA overexpression may play an important role in the carcinogenesis of OSCC and can be a potential molecular marker of OSCC.
